old 220 cummins , too much smoke no power
ols 220 cummins ,no power ,sooty smoke ,smolder a little when hot 180 deg.
not overheat,no fuel starve , rolls coal like ocean liner ,on hill
not near power should have even for non turbo guttless 220
what is issue ,plug injector ,stuck valve ,bad ring ,low commpression
or all ,this was supposedly rebuilt Quotation marks .
Save and fix of junk it ,reengine verticle N14 isx stack out roof?
on the positive the coach is spectacular,clean even comes with parents
